A new study by Tulane University researchers, published in the March edition of Molecular Endocrinology, provides insight into one of the ways diethylstilbesterol (DES) may alter the development of the uterus.
DES, a synthetic estrogen, was prescribed to prevent miscarriage in many women who were pregnant between 1941 until 1971. In 1971, DES was banned in the United States due to concerns about the occurrence of cancer and infertility in the daughters of women who took it.
“Several millions of pregnant women were treated with DES and we have continued to study and model the disease since it provides unique insights into what estrogenic chemicals may do to the developing fetus,” says study co-author John McLachlan, director of the Center for Bioenvironmental Research at Tulane and Xavier Universities. “There are other chemicals in our environment -- the results of industrial, agriculture and chemical processing -- that, while their estrogenic affect is weaker, may affect developing embryos in the same way. We need models to understand the cellular and genetic mechanisms by which environmental chemicals work. This study is a step in that direction.”

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
